PSA-70Xi
Unparalleled Performance and Convenience in Cold Properties Testing
State-of-the-Art Solution
The world’s first and only automatic pour, cloud and freezing point analyzer – all in a single unit – that significantly increases lab productivity and improves profitability by providing quick, precise results
Product Overview
PAC Powered by Phase Technology’s 70Xi cold flow properties analyzer significantly increases lab productivity and improves profitability by providing quick, precise results. The 70Xi analyzer helps minimize giveaway and ensure that released product is on spec.
Phase Technology users can be confident that their test results accurately meet and comply with ASTM International standards for pour, cloud and freeze point: ASTM D5949, D5773 and D5972. The oldest, continuously-in-use cold flow methods in the industry!
The PSA-70Xi is the world’s only analyzer that performs pour, cloud and freeze point in one unit. Combining functions saves money and valuable bench space in the lab.
In addition to manual pipette, the 70Xi is available in single shot or with a 48-station autosampler, which allows unattended testing. Users can initiate 1 to 48 runs in a row, then walk away and let the analyzer do the rest.
